ある。To ensure that the area located in front of or below the bearing bracket or bearing plate is also excavated, hinged digging teeth are located along the adjacent edges of the digging wheel hub, which hinged digging teeth are in the extended position. Enter the soil in the traveling direction of the excavated plate. The fact that the hinged cutting teeth move only in a predetermined direction allows the hinged cutting teeth to be automatically pivoted into the actuated position by soil pressure during the advancement of the drilling wheel. Such an arrangement is in most cases reliable in its operation, but in particular soils, the pivoting movement may not occur in the necessary and desirable manner.

て行かれるようにすることによって解決される。Means and Actions for Solving the Problems According to the present invention, this problem is due to the fact that the hinged digging tooth is constructed in a two-arm type with a rear control arm and an outward milling tooth, in the form of a gear. A control arm that is a guided member of a mechanism (a mechanism including a guide member provided on a bearing bracket and a guided member that is guided by the guide member by rotation of an excavation wheel provided on a hinge-coupled excavating tooth), The solution is to ensure that the hinged digging tooth is always brought to the swung position.

によって固定される。換言すれば、これはカム制御と呼
ぶことができる。Therefore, the present invention uses the principle that the action and displacement of the hinged excavating tooth is performed independently of the soil backpressure by means of a positive force control. Therefore, the present invention has the advantage that the soil or rock can be reliably excavated in the direction of travel of the bearing bracket and thus an optimum advance can be made.
The gear-like mechanism smoothly guides the hinged cutting teeth, and the deflection path of the hinged cutting teeth is fixed by the slope of the control surface. In other words, this can be called cam control.

ッジを通過して移動したときに前記制御用面と係合し、
この制御レッジの長さが変位時間を決定する。According to a preferred construction of the invention, the gear-like mechanism is arranged on a bearing bracket along a circular sector coaxial with the first control surface facing in the circumferential direction on the control arm and the drilling wheel. And the control ledge engages the control surface when the corresponding hinged drilling tooth moves past the control ledge during rotational movement of the drilling wheel,
The length of this control ledge determines the displacement time.

しの両方で、ヒンジ結合掘削歯の軸受が急激な運動によ
るストレスを受けることがない。It is also advantageous to provide the control arm with a control surface that can enter and exit in the circumferential direction. In this case, the bearing of the hinged excavating tooth is not subjected to stress due to abrupt movement during both swing-back and swing-out.
また、ヒンジ結合掘削歯の変位のためのカム状形態を設
けても有利となる。It would also be advantageous to provide a cam-like configuration for displacement of the hinged drill teeth.

れるようにしてある。According to another configuration of the gear-like mechanism, the gear-like mechanism has a control surface extending radially on the control arm and a control ledge arranged on the bearing bracket for engaging the control surface. The control ledges are arranged on paths with different radii so that the control ledges are guided radially along the control surface during rotation of the hinged drill teeth or the drill wheel.
ヒンジ結合掘削歯と軸受ブラケットの間の間隔を補正す

もなお、自在軸受をハブにできるかぎり接近させて配置
することができる。According to another preferred configuration of the invention, the control arm is guided inside the hub through an opening in the drilling wheel hub and engages the control ledge at the end face of the hub. This means gives the control arm a relatively long structure,
While it is possible to increase the leverage of the teeth, the universal bearing can nevertheless be located as close to the hub as possible.

は前記ハブの安定した構造により特に頑丈でもある。It is particularly suitable to use the edge of the hub opening as a rear stop for the control arm. This stop must absorb the advancing pressure acting on the milling teeth, but can be constructed in the simplest way without any extra precautions. This arrangement is also particularly robust due to the stable construction of the hub.
